FPGA verilog PS2 鼠标控制LED   PS2接收模块（电脑接收，鼠标发送） PS2_CLK信号由PS2设备产生,即鼠标在产生时钟的同时向主机送出数据，主机在PS2_CLK信号的下降沿读取(锁存)每个位。/*标准的鼠标有两个计数器保持位移的跟踪:X位移计数器和Y位移计数器。**可存放9位的2进制补码，并且每个计数器都有相关的溢出标志。**它们的内容连同三个鼠标按钮的状态一起以三字节移动数据包的形式发送给主机。**位移计数器表示从最后一次位移数据包被送往主机后有位移量发生。**位移计数器是一个9位2的补码整数。它的最高位作为符号位出现在位移数据包的第一个字节里。

本程序是串口芯片TLC16c752的典型操作代码，可以在此基础上编写自己的串口程序--The codes for typical operations on serial chip TLC16c752. You could write your own serial port applications based on it.

Perfect Example for Embedded-C begineers Explaining use of Data types, Storage class specifiers. The following code will not immediately run. After being debugged, you are to run this code in the MPLAB environment as outlined in the procedure. This code, when working, will be a very simple program that initializes two variables, runs a loop, and stops. The variables are Fahrenheit and Celsius representing the two common units of Temperature. The loop walks Fahrenheit through all integers between -212.0 and +212.0 while setting the respective Celsius value each step of the way.-Perfect Example for Embedded-C begineers Explaining use of Data types, Storage class specifiers.
